All,

I'm not completely new to SCO UnixWare, however I have an old 2.1.2 box that
has one NIC, two IP addresses (for two LAN networks) and I have lost
connectivity on the second IP. That is it won't connect to any other box on the
second LAN address.

The LAN is setup as:


Nat Alex net: 10.79.0.0/16 <--- the box's first LAN
Morehead net:10.153.0.0/16 <--- read below for the explanation
Nat Alex Gateway IP: 10.79.1.1
Morehead Gateway IP: 10.153.1.1
ETR server IP: 10.79.100.200 <--- This is the box I need to "fix"
ACI_NET IP (ACI0): 192.168.79.50 <--- this is the second LAN IP address
(see confnet.d/inet/interface below)
ACM device IP: 192.168.79.54 <--- this is a device I need to
connect to on the second LAN

I had to add the default gateway address of 10.79.1.1 to the SCO box and
ultimately a static route to 10.153 so that hosts on the Morehead LAN would be
able to connect to the SCO box. In doing so I have broken the connectivity to
the ACI_NET LAN (192.168). I need the SCO box to connect to the ACM device IP
of 192.168.79.54, but I can't now.

Heres some information I've collected: ( "<---" are annotations for what I've
added)

#Field Name Verify Purpose Default on NULL

#$4 device string full device path name NONE

# ifconfig prefixunit# Converted_Address ifconfig_opts up
# Converted_Address is the /etc/inet/hosts value for the address field.
# So ifconfig_opts has the -trailers and other options needed by
# System V Release 4 transport providers.
# Note that a null entry is allowed for providers like lo0 that require
# no additional ifconfig options at boot time.

# The slink_opts value is used by slink to initialize the device

# slink_opts selects the strcf function from /etc/inet/strcf and
# any initial arguments.
# add_interface is the default slink_opts value; it is used with
# Ethernet-style devices.
# Additional arguments will be appended to slink_opt to make the final
# form of the slink operation:
# slink_opts ip device prefixunit#
# Where ip will be an open file descriptor to /dev/ip and device prefix
# and unit are defined in the current interface entry.
# For a standard Ethernet board, slink_opts may be null; the defaults
# will take care of all arguments.

Question is, what's the issue that I can't get connectivity on the 192.168 LAN
to and from this box? Any ideas?

(BTW, I do have UNIX experience (Linux, BSD, SysV, IRIX, SCO, Solaris, etc), I
understand how to get things done on a UNIX box -- just not this one)
